400 session not found : Failed to process the request:Request refers to an unknown session

[prasad]

Dear Team,

Here I am configuring NWDI 7.3.

Successfully created a standalone Developmenmt configuration and while synchronizing the services using CM services the screen throws an error

( on clicking any button on the synchronize service screen I am getting same error)

400 session not found

Failed to process the request:Request refers to an unknown session

Thru SDN got the below link and checked the parameters.Our AS JAVA version is 7.31 and the parameters are already set to false.

http://wiki.sdn.sap.com/wiki/display/TechTSG/(JSTTSG)(Web)Problems-P203

Please help on this

Regards

Prasad

Hi Prasad,

I think this is not necessarily an NWDI problem. In order to see why the webdynpro session becomes unknown, an HTTPTrace would be required.

Please suggest me on this where the actual error is being thrown

below is the error shown in log files.

The received security session id related cookie is not valid. The current request will be isolated in a new session. There might be a few reasons causing this behavior: 1) Possible session fixation hacker's attack.  2) The received security session id cookie is already outdated. One possible solution is increasing the value of the 'SecuritySessionIdGracePeriod' servlet_jsp property. For more information read SAP Note 1464914. 3) No security session id cookie is sent (over http) because it is protected via custom configuration of the http service properties 'SecuritySessionIDHTTPSProtection' and 'SystemCookiesHTTPSProtection'. Revise the configuration of the http service properties or adapt the problematic scenario accordingly.

Prasad

Hi,

most likely I will forward this thread to an AS Java related forum but before that could you please check if this note helps?

Hi Prasad,

I'm facing the same problem.

In our NW 7.3 we are creating a Development Configuration to create a custom DC.

We cannot synchronize SCs so we can't work in NWDS properly.

Have you solved the problem??

Is there any way to check in SCs in development conf. manually? (As we did in previous versions when using tracks)

Best Regards,

Jorge Linares

Dear Jorge,

Here we are facing the same issue. we have  raised a OSS to SAP and it is still under process.

Prasad.

[Former Member]

Hi Prasad,

did SAP provide you some help on this?

I also try to configure CM Services and get the same error.

Did you already upgrade to 7.31?

Thanks in advance!
